RESTUBE is a product for better water safety, where no similar lifejackets have previously been used. In a little more detail: RESTUBE is an inflatable backup when you’re in water. Small and light, your RESTUBE is always there. Easily attached around your waist or on a harness and off you go. When necessary, pull hard on the trigger and the float inflates. Now you have time. Perfect for use in a lake or in the ocean. Reusable through replacing the gas cartridge.
